A survey report in which the main models for calculating the complex permittivity (CP) of moist heterogeneous mixtures are presented. A method for measuring the temperature dependence of the CP spectra of moist mixtures using a coaxial container in the frequency range from 15 MHz to 15 GHz is considered, using the example of mineral soils. A mixture model is described that takes into account frequency, temperature, humidity, and texture.
